Each record captures the characteristics of one energetic neutral atom arriving at IBEX-Hi. Included is a time tag (seconds since 00:00 UT of January 6, 1980), an arrival direction (R.A. and Dec. in J2000 celestial coordinates), the IBEX location, ENA energy band and coincidence type. Positive species identifications are not made, but most arriving ENA's are hydrogen atoms. Data files are given for each 8-day orbit and for each of the 6 IBEX-Hi energy bands. The data files are in ASCII.

As of this writing (11/5/2010), this product had been issued by the IBEX team in two releases. Release 1 IBEX-Hi map data are superseded by Release 2 data which are more time-extensive (12 months vs. 6 months) and are richer in content. While Release 1 IBEX-Hi map data and their documentation remain accessible at ftp://spdf.gsfc.nasa.gov/pub/data/ibex/hi/maps/digital_data/release_1/ and ftp://spdf.gsfc.nasa.gov/pub/data/ibex/hi/maps/images/release_1/, this description supports the retrieval and use of Release 2 data only. The Release_2 IBEX-Hi map data contain all-sky 6 deg x 6 deg resolution maps in J2000 ecliptic coordinates of energetic neutral fluxes reaching the near-Earth IBEX spacecraft from the distant heliosphere and heliosheath. Maps are in both a spacecraft frame and, via Compton-Getting corrections, a heliospheric frame. Basic maps are each accumulated over 6-months duration, so far for epochs 1 (12/2008-06/2009) and 2 (06/2009-12/2009). Maps are available for five of the energy bands of IBEX-Hi (0.52-0.95, 0.84-1.55, 1.36-2.50, 1.99-3.75, 3.13-6.00 keV) and, for the heliospheric frame only, also for six monoenergetic points (0.71, 1.11, 1.74, 2.73, 3.0, 4.29 keV). In addition, monoenergetic maps are available as summed over the data collected during epochs 1 and 2 combined. All maps are available in digital text format and in PNG image format (considered as separate data sets within VEPO). Given that VHO/VEPO typically displays clickable granule (file) names for any given specification of data product and time span, and given that IBEX-Hi digital maps and PNG-formatted display maps are each considered single data products, a request for data from either product will yield .GE.20 names of files containing data spanning or within the requested time span. For IBEX, the names shown by VHO/VEPO actually have the form subdirectory/filename. The subdirectories are named map1, map1cg, map2, map2cg, and map-combined. Maps involving "1" ("2") are from the first (second) 6-month epoch, while "combined" means composed of data taken during epochs 1 and 2. Maps involving (not involving) "cg" means heliospheric frame (spacecraft frame). In the first four subdirectories, file names are of the forms ha60.hide-trp-flux100-hi-N-flux.ext and ha60.hide-trp-mono_80-P.PP-flux.ext, where "ext" is "png" or "txt" according to which product is requested, N is the energy step number for the IBEX-Hi instrument (2-6), P.PP is the energy level, in keV, of a monoenergetic flux. Files in the "combined" subdirectories are named "combined-P.PP-flux.ext, where P.PP has the same meaning as above. In addition to the flux maps to which VEPO provides access, several map files whose data support the determination of the fluxes are also available in the underlying nssdcftp directories and are described by aareadme files there (and by IBEX web pages at SWRI: http://ibex.swri.edu/ibexpublicdata/Data_Release_2/)

The time spans are selected to support analysis of the flow latitude of the interstellar medium (ISM). The data are specifically as used in the analyses reported in Bzowski et al (2012) and Mobius et al (2012). A companion product has the counting data used in the ISM flow longitude analyses of the same papers. Data are organized into orbit-specific arrays wherein the columns contain the counts for a given time span within the orbit and the rows contain the counts for a given one of the 30 spin-phase angles for the multiple time spans of the orbit. Arrays are available for orbits 12-19, 60, 61, and 63-67. The number of time spans used in an orbit varies from 5 to 38.

This data set consists of images of thermospheric O/N2 column density ratios at 2-min resolution during times of strong geomagnetic storms (Dst.LT.-80nT) of 2000-2005. The ratios are generated from dayside airglow observations of the IMAGE Far Ultraviolet (FUV) Spectrographic Imager (SI). The SI has a peak response at the OI 135.6 nm oxygen emission line and a bandpass of 131.0 to 140.0 nm which includes the LBH band from N2 molecules. For each O/N2 plot, there is a plot of the SI image from which the O/N2 plot was generated, and there is an IDL saveset of the content of the O/N2 maps. The Information URL of this descriptor identifies detailed discussions of the derivations of O/N2 rations from the SI images.

The Ultraviolet Imager (UVI) is a small camera that detected and produced images of the ultraviolet light of the aurora, day and night. Key Parameter (KP) images are calculated at nominal 5-10 minute intervals at spacecraft altitudes above 6 Re. The UVI KP image is background subtracted and calibrated to radiance values (photon cm^-2 cm^-1). The data is a rectangular two-dimensional array (228 rows x 200 columns). Only a circular region of the rectangular array contains valid image data. The UVI KP Image Archive (http://tideuvira.nsstc.nasa.gov/uvi/kpgs-Data.htm) allows the user to look at all the KP Mosaics for a selected month. The gif or png plot files contain the up to 35 KP images taken with the LBHL filter. Reference images are also provided showing the location of the UVI field of view relative to continental outlines.
